A:Answer Hey there, and thanks for your interest in this attractive rangetop! At this time, we are not able to comment on materials used in certain specific parts; we regret any inconvenience that may cause. We strive to create our appliances using high quality, durable materials, and all our products also meet safety and environmental standards. We can advise the right front burner is the only one that varies in appearance from the others – it can have either a copper or black finish on the burner ring. The cooktop surface is porcelain-enamel. The material of the burner grates is porcelainized cast iron/heavy cast. We hope this information is useful for you, and are glad to assist if you have any other questions or concerns. We wish you all the best! -Sarah@Café
